PUMPING OUTFIT.

Application filed December 11, 1924. Serial No. 755,230.

i 10 all whom it may concer/ft.

lie it known that I, CLYDE Molrssron, a citizen of the United States, residing at Maxine, in the county of Tulsa and State of klahoma, have invented certain new and useful improvements in a Pumping Outfit, of which the following is a specification.

This invention relates to improvements in pumping outfits, and is more particularly adapted to a means for increasing theV power stroke of the pump rod where-by the elfe ciency in the operation of the pumping mechanism is increased without necessitating the increase of the power necessary to operate the saine.

One of the important objects of the present invention is to provide means in connection with the upper end of the usual pump rod and the walking beam and sup porting standard therefor for facilitating the increase of the `strokes of the pump rod, means being further provided for adjusting the length of the strokes.

A further object of the invention is to provide a pumping outfit of the above mentioned character, which is simple in construction, inexpensive, strong and durable and furthermore .adapted for the purposes for which it is designated.

Other `objects and advantages of this invention will become apparent during thel course of the following description.

In the accompanying .drawing forming a part of this specification and in which like numerals designate like parts throughout the same:

Figure 1 is a side elevation, and

Figure 2 is a top plan view.

In the drawing wherein for the purpose of illustration is shown the preferred embodiment of my invention, the numeral 1 designates the base which supports the standard or post 2. Suitable bracing means is provided therefor, the same being iii'dicated at A walking beam 4 is pivotally supported intermediate its ends on the upper end of the standard post 2 as illustrated at 5 and is adapted for oscillatory movement thereon in the manner well known in the art. The upper end of the usual pump rod of a pumping'mechanism is illustrated at 6 and carried thereby is the head 7 which supports a pulley 8.

A transversely extending shaft 9 is supported in a suitable bearing 10 mounted on the forward end of the walking beam 4 and carried by the shaft on opposite sides of the walking beam are the pulleys 11 and 12 respectively. As is clearly shown in the drawing, the pulley 8 associated with the head 7 which is mounted on the upper end of the pump rod 6 is disposed at substantially right angles to the pulleys 11 and 12. An additional pair of pulleys 13 and 14 are carried by the transversely extending shaft 15 the latter' beingsupported on the standard or post 2 adjacent the lower end thereof so that the pulleys 13 and 14 are disposed on the opposite side of the post, the pulley 13 being in alignment with the pulley 11 while the pulley 14 is in alignment with the pulley 12. This construction isy more clearly illustrated in Figure 2.

A. wire cable 16 is looped intermedi-ate its ends, and the looped portion 17 is disposed over the pulley 8 supported in the head 7. The ends of the wire cable 16 extend over the alignment pulleys supported on Ythe forward end of the walking beam 4 and the lower portion of the standard or post 2 respectively in the manner clearly illustrated in the drawing. The free ends of the cable 16 are detachably associated with a pair of hooks 18 and 19 respectively.

The hooks are arranged in opposed relation and are adapted for engagement with the notches 20 provided in the upper edge of the forward portion of the walking beam 4 whereby the length of the stroke of the pump rod may be adjusted, it being understood of course that the hooks are .adapted to be removably disposed in any o-ne of the notches and when positioned therein will be prevented from accidental disengagement therefrom, thus holdingthe cable in proper position.

A crank shaft L21 is journaled in suitable bearings associated with .a pair of :support- It is obvious from the construction shown that when the walking beam a is operated, the strokes of the pump rod 6 will manifestly be increased through the medium of the cable 16 and the pulleys associated therewith. As heretofore stated, by moving the hooks from one notch to another, the length of the stroke may be increased as is desired. The provision of a pumping outfit of the above mentioned character, will increase the eiciency of the operation of the pumping mechanism with the use of less power.

iVliile I have shown the preferred embodiment of my invention, it is to be understood that various changes in the size, shape and arrangement of parts may be resorted to Without departing from the spirit of the invention and the scope of the appended claims.

Having thus described the invention, what I claim is l. In combination, a supporting standard, a walking beam pivotally supported intermediate its ends thereon, a pump rod, a pulley supported on the upper end thereof, a pair of pulleys on the forward end of the walking beam, an additional pair of pulleys supported on the lower portion of the standard, a cable looped intermediate its ends, the looped portions thereof being disposed over the'pulley on the pump rod, the free ends of the cable extending over the aligning pulleys on the beam and standard respectively, means for securing the free ends of the cable to the forward portion of the beam, and means associated with the rear end of the beam for oscillating the same.

2. In combination, a supporting standard, a walking beam pivotally supported intermediately its ends thereon, a pump rod, a pulley supported on the upper end thereof, a pair of pulleys on the forward end of the walking beam, an additional pair of pulleys supported on the lower portion of the standard, a cable looped intermediate its ends, the looped portions thereof being disposed over the pulley on the pump rod, the free ends of the cable extending over the aligning pulleys on the beam and standard respectively, means associated with the free ends of the cable and the forward portion of the walking beam for holding the free ends of the cable at various positions on the forward portion of the beam, and means associated with the rear end of the Walking beam for oscillating the same.

3. In combination, a supporting standard, a walking beam pivotally supported intermediate its ends thereon, a pump rod, a pulley supported on the upper end thereof, a pair of pulleys on the. forward end of the walking beam, an additional pair of pulleys supported on the lower portion of the standard, a cable looped intermediate its ends, the looped portions thereof being disposed over the pulley on the pump rod, the free ends of the cable extending over the aligning pulleys on the beam and standard respeetively, means associated with the free ends ofthe cable and the forward portion of the walking beam for holding the free ends of the cable at various positions on the forward portion of the beam, said means comprising hooks associated with the free ends of the cable and arranged in opposed relation, and adapted for engagement with notches arranged in spaced relation on the upper edge of the forward portion of the walking beam, and means associated with the rear end of the walking beam for oscillating the same.

4. In combination, a supporting standard, a walking beam pivotally supported intermediate its ends thereon, a pump rod, a head carried by the upper end thereof, a

pulley supported thereon, a pair of pulleys Y supported on the forward end of the walking beam on the opposite side thereof, an"

additional pair of pulleys supported on the lower portion of the standard on opposite sides thereof and arranged in alignment with the aforementioned pair of pulleys, a wire cable looped intermediate its ends, the looped portion of said cable being disposed over the pulley or said head, the free ends of the cable extending over the aligning pulleys on the forward end of the walking beam and supporting standard respectively, a pair of hook members associated with the free ends. of the cable and disposed in opposed relation, said hook members adapted for engagement with notches arranged in the upper edge of the forward portion of the walking beam, and means associated with the rear 'end of the walking beam for oscillating the same.

In testimony whereof I afIiX my signature,

CLYDE MCKISSICK.
